Description
Technical field
The utility model relates to a kind of explosion-proof high-pressure solenoid valve, exactly is the special-purpose explosion-proof high-pressure solenoid valve in a kind of colliery.
Technical background
On the existing market mostly the solenoid valve working medium pressure all below 2.5MPa, and at the pressure of deep layer down-hole high pressure working medium at least more than 4MPa, do not reached job requirement far away, thus existing solenoid valve cisco unity malfunction.
The utility model content
The utility model purpose is at existing defective, provide a kind of job requirement that not only can be implemented in the high-pressure medium pressure of deep layer down-hole 4-10MPa to people, and move the special-purpose explosion-proof high-pressure solenoid valve in accurate, reliable, sensitive, simple in structure, with low cost colliery.
The utility model comprises valve bonnet, places electromagnetism starting arrangement and valve body in the valve bonnet, it is characterized in that:
A, electromagnetism starting arrangement comprise electromagnetic coil, resistance magnetic core and moving iron core, the electromagnetic coil upper end is fused by housing screw and iron core sleeve by line bank, the underpart is welded to form the flame proof body with the sleeve pressing plate that is fixed in valve body by seal ring sealing and pressing plate housing pin, resistance magnetic core and iron core sleeve are integrally welded, with in the moving iron core top that resistance magnetic core underpart is connected Returnning spring is housed, moving iron core lower side has a unloading hole that is communicated with it, forms guide's valve chamber between moving iron core and iron core sleeve;
B, body valve comprise valve seat and valve body, the valve seat both sides are respectively equipped with the inlet/outlet pipeline, the inlet/outlet pipeline is communicated with into and out of stomatodeum with the guide who is communicated with valve body pilot valve chamber by the hollow locating stud respectively, have one between valve seat and valve body by bowl-type dish, the fixing diaphragm pad of rivet, the upper-end surface of diaphragm pad is equipped with a turriform spring.
In addition, described resistance magnetic core length is 20～23mm, and moving core length is 28～32mm.
Described guide's exit ramp internal diameter is 1～1.5mm, and the outstanding valve body recess end face height in guide's exit ramp road junction is 2.8～3.2mm.
The internal diameter of described unloading hole is 2～2.5mm.
Working principle: when the special-purpose explosion-proof high-pressure solenoid valve in colliery uses, behind the defeated connecting leg road of engage thread connection, high-pressure fluid medium enters guide's valve chamber and valve body by the valve body inlet passage by guide's entrance driveway, valve body diaphragm pad is produced down pressure, when the diaphragm pad flows to the valve body outlet conduit when high-pressure medium by guide's exit ramp, under because of inconsistent pressure reduction that produces of two stomatodeum internal diameters and turriform spring action, be in normally off.Opens solenoid valve, the electromagnetic coil energising, the resistance magnetic core produces magnetic field, will move iron core and pick up, and opens guide's exit ramp, medium is discharged by the pilot valve exit ramp in the indoor and valve body of pilot valve, pressure reduces in the valve body, acts on diaphragm pad pressure and diminishes, and promotes the diaphragm pad and move upward under the upstream pressure effect, open pipe passage, valve body is opened.When closing solenoid valve.The electromagnetic coil outage, the resistance magnetic core quits work, moving iron core resets by action of reset spring, and guide's valve chamber is closed, along with closing of guide's valve chamber, valve body slowly is full of water, when pressure is consistent about the diaphragm pad by the time,, the diaphragm pad is moved downward because the turriform spring action makes the effect of being stressed of diaphragm pad upside, the passage of blinding off a line, valve body is closed.
Effect of the present utility model
1, the utility model not only can be implemented in the job requirement of the high-pressure medium pressure of deep layer down-hole 4-10MPa, and owing to adopted antetype diaphragm formula structure, change by resistance magnetic core and moving core length simultaneously, make core length reduce 5～7mm, make it to be in electromagnetic coil and produce the highest optimum bit of magnetic force, do not change under electromagnetic power and the high pressure conditions thereby be implemented in, the electromagnetism actuating section just can be opened neatly.Again guide's exit ramp internal diameter is decreased to 1～1.5mm, and to make the outstanding valve body recess end face height in guide's exit ramp road junction be 2.8～3.2mm, with reduce high-pressure medium by the time to pressure reduction that valve body was produced, make that acting on the diaphragm chamber pressure reduces, promoting the diaphragm die-cushion under the upstream pressure effect moves upward, thereby open pipe passage easily, valve body is opened convenient, therefore improves electromagnetic attraction and change pressure reduction that to reach the solenoid valve action accurate, reliable, sensitive.
2, the utility model is novel, and is reasonable in design, simple in structure, with low cost.
